Surface Complex Formation Data:

Mineral: Anatase
Reference: S05
SCM Type: TL - Triple Layer
Ligand: NO2<1-> - nitrite
Site Type: »Ti-OH
Equation: »Ti-OH + NO2<1-> + H<1+>  ⇔  »Ti-OH2-NO2
LogK: 8.2         LogK2.31 nm−2 (SSD-normalized):   8.54
Experiment: Literature
Ionic Strength: 1.0 mol/L
Temperature: 298.15 K
Fit Method: Unknown
Comment: calculation from literature values with standard SSA and SSD at ionic strength of 1M »Ti-OH2<1+> + NO2<1-> = »Ti-OH2-NO2 logK = 5.4 »Fe-OH + H<1+> = »Fe-OH2<1+> -pK1 = logK = 2.8 sum »Ti-OH + NO2<1->+ H<1+> = »Ti-OH2-NO2 logK= 5.4+2.8 = 8.2
